i had this problem.. first i thought it was my shiftet rattling.. but that was not the case...

try removing all the timing pulled in your traction control timing retard.... i did this and i think it is the traction control just pulling timing and giving false knock readings

If I'm not mistaken, there are PIDs in HPTuners to see what exactly is pulling the timing. Someone correct me if I'm wrong...

Yeah you can track what is pulling the timing also check your knock sensor values against a late model stock tune. Often the older years have shocking values here which can cause timing to be pulled for no apparent reason.

What year is the car, how many miles on it, maybe bad knock sensors, 98 cars are known for it...
